Abstract

The invention discloses digging equipment, which relates to a digging device. An outer sleeve (20) of an ultrasonic vibration rotary digging machine is fixed on a fixed bottom plate (29); the fixed bottom plate is connected with a linear rolling guide rail pair (38) arranged on an upright post (31) on one side of the upper part of a frame (36); upright posts at the upper and lower ends of the linear rolling guide rail pair are provided with an upper limiting position (32) and a lower limiting position (35) respectively; the upper part of the fixed bottom plate (29) is connected with counterweights (30) on the other sides of the upright posts through chains; the middle parts of the chains are sleeved on a main shaft elevating transmission chain device (33); a power wheel (27) on the upper part of the ultrasonic vibration rotary digging machine is externally connected with a power mechanism (3); an ultrasonic generator and an operation box (34) are arranged on the frame; and a lower frame of a digging drill (10) at the lower end of the ultrasonic vibration rotary digging machine is provided with a corresponding workbench. According to the digging equipment, an ultrasonic vibration principle is combined with an auxiliary workbench, so that silicon rods or sapphire rods dug out of the workbench have high accuracies.

Description

【Technical field】 [0001] The invention relates to a digging device for workpieces, in particular the invention relates to a dredging equipment for polysilicon, single crystal silicon and sapphire rod-shaped materials through ultrasonic vibration and rotation. 【Background technique】 [0002] It is known that about 60% of polysilicon solar cells in the photovoltaic market are based on polysilicon wafers. Therefore, the use of polysilicon wafers is extremely huge, which can be described as the core force of the photovoltaic industry; but to manufacture qualified Silicon wafers, especially round silicon wafers, mostly need to be wire-cut through round silicon rods to form silicon wafers that meet the specified requirements. The existing method is to form large silicon ingots into fragments by beating them, and then use a crucible to Melting, use the seed crystal of the guided crystal to draw silicon rods close to the requirements, and obtain the silicon rods with the required ro...
